创建httpTool.swift 网络请求工具类

import UIKit//请求方法/// - GET:  get/// - POST: postenum RequsetMethod:String {    case GET = "GET"    case POST =  "POST"}class httpTool: AFHTTPSessionManager {    //单例    static let sharedTools:httpTool = {        let instance = httpTool()        instance.responseSerializer.acceptableContentTypes?.insert("text/html")        instance.responseSerializer.acceptableContentTypes?.insert("text/plain")        return instance    }()     // 定义请求完成的回调的别名    typealias httptoolBack = (response:AnyObject?,error:NSError?)->()    /// 请求数据    ///    /// - parameter urlString:  请求地址    /// - parameter parameters: 请求参数    /// - parameter finished:   请求成功或者失败的回调    func request(method: RequsetMethod = .GET, urlString: String, parameters: AnyObject?, finished:httptoolBack){        // dataTaskWithHttp 是写在 .m 文件里面的        // 对应在 Swift 中的，就是 private 修饰的方法        // 定义请求成功的闭包        let success = { (dataTask: NSURLSessionDataTask, responseObject: AnyObject?) -> Void in            finished(response: responseObject, error: nil)        }        // 定义请求失败的闭包        let failure = { (dataTask: NSURLSessionDataTask?, error: NSError) -> Void in            finished(response: nil, error: error)        }        if method == .GET {            GET(urlString, parameters: parameters, progress: nil, success: success, failure: failure)        }else{            POST(urlString, parameters: parameters, progress: nil, success: success, failure: failure)        }    }    /// 发送请求(上传文件)    func requestWithData(data: NSData, name: String, urlString: String, parameters: AnyObject?, finished:httptoolBack) {        // 定义请求成功的闭包        let success = { (dataTask: NSURLSessionDataTask, responseObject: AnyObject?) -> Void in            finished(response: responseObject, error: nil)        }        // 定义请求失败的闭包        let failure = { (dataTask: NSURLSessionDataTask?, error: NSError) -> Void in            finished(response: nil, error: error)        }        POST(urlString, parameters: parameters, constructingBodyWithBlock: { (formData) -> Void in            formData.appendPartWithFileData(data, name: name, fileName: "aa", mimeType: "application/octet-stream")            }, progress: nil, success: success, failure: failure)    }}

发送post请求

 //创建httpTool 实例        let TabHttpTool = httpTool.sharedTools        //创建请求参数        let params = ["username":"invest","password":"123456"]        //发送psot请求        TabHttpTool.request(RequsetMethod.POST, urlString: "http://api....../login", parameters: params) { (response, error) in            print(response)        }

服务器返回结果
